This tab of the Global Preferences window provides access to advanced Duplicate File Detective settings.
| • | Suppress retrieval of file ownership information - File ownership data is automatically retrieved from duplicate files for display within the duplicate report (upon search completion). Extraction of this information can slow duplicate search performance, especially when scanning remote (network) paths. If you don't care about file ownership, you may engage this switch to suppress its collection (file ownership fields will always be displayed as "unknown"). |
| • | Number of threads used during file content hashing operations - Can be set to "determine automatically" (recommended) or a specific number of threads. |
Tip: Multiple file content hashing threads are generally most effective at speeding up duplicate file comparison operations when the current project is configured to scan multiple, discrete volumes (e.g. paths spanning multiple physical disks or multiple network paths). Using large numbers of threads to hash files located on a single physical volume will usually only serve to reduce performance, and is not recommended.
| • | Maximum image preview file size (in KB) - Image files selected within the report detail view will be previewed only if their file size is less than what's defined here. Default value is 102,400 KB (100 MB). |
